The present invention relates generally to medical methods, devices, and systems. In particular, the present invention relates to methods, devices, and systems for the endovascular, percutaneous or minimally invasive surgical treatment of bodily tissues, such as tissue approximation or valve repair. More particularly, the present invention relates to repair of valves of the heart and venous valves.
Surgical repair of bodily tissues often involves tissue approximation and fastening of such tissues in the approximated arrangement. When repairing valves, tissue approximation includes coapting the leaflets of the valves in a therapeutic arrangement which may then be maintained by fastening or fixing the leaflets. Such coaptation can be used to treat regurgitation which most commonly occurs in the mitral valve.
Mitral valve regurgitation is characterized by retrograde flow from the left ventricle of a heart through an incompetent mitral valve into the left atrium. During a normal cycle of heart contraction (systole), the mitral valve acts as a check valve to prevent flow of oxygenated blood back into the left atrium. In this way, the oxygenated blood is pumped into the aorta through the aortic valve. Regurgitation of the valve can significantly decrease the pumping efficiency of the heart, placing the patient at risk of severe, progressive heart failure.
Mitral valve regurgitation can result from a number of different mechanical defects in the mitral valve or the left ventricular wall. The valve leaflets, the valve chordae which connect the leaflets to the papillary muscles, the papillary muscles or the left ventricular wall may be damaged or otherwise dysfunctional. Commonly, the valve annulus may be damaged, dilated, or weakened, limiting the ability of the mitral valve to close adequately against the high pressures of the left ventricle.
The most common treatments for mitral valve regurgitation rely on valve replacement or repair including leaflet and annulus remodeling, the latter generally referred to as valve annuloplasty. A recent technique for mitral valve repair which relies on suturing adjacent segments of the opposed valve leaflets together is referred to as the “bow-tie” or “edge-to-edge” technique. While all these techniques can be very effective, they usually rely on open heart surgery where the patient's chest is opened, typically via a sternotomy, and the patient placed on cardiopulmonary bypass. The need to both open the chest and place the patient on bypass is traumatic and has associated high mortality and morbidity.
For these reasons, it would be desirable to provide alternative and additional methods, devices, and systems for performing the repair of mitral and other cardiac valves. Such methods, devices, and systems should preferably not require open chest access and be capable of being performed either endovascularly, i.e., using devices which are advanced to the heart from a point in the patient's vasculature remote from the heart or by a minimally invasive approach. Further, such devices and systems should provide features which allow repositioning and optional removal of a fixation device prior to fixation to ensure optimal placement. Still more preferably, the methods, devices, and systems would be useful for repair of tissues in the body other than heart valves. At least some of these objectives will be met by the inventions described hereinbelow.
Minimally invasive and percutaneous techniques for coapting and modifying mitral valve leaflets to treat mitral valve regurgitation are described in PCT Publication Nos. WO 98/35638; WO 99/00059; WO 99/01377; and WO 00/03759.

The invention provides devices, systems and methods for tissue approximation and repair at treatment sites. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the abdomen, thorax, cardiovascular system, heart, intestinal tract, stomach, urinary tract, bladder, lung, and other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site. In addition, many of the devices and systems of the invention are adapted to be reversible and removable from the patient at any point without interference with or trauma to internal tissues.
In preferred embodiments, the devices, systems and methods of the invention are adapted for fixation of tissue at a treatment site. Exemplary tissue fixation applications include cardiac valve repair, septal defect repair, vascular ligation and clamping, laceration repair and wound closure, but the invention may find use in a wide variety of tissue approximation and repair procedures. In a particularly preferred embodiment, the devices, systems and methods of the invention are adapted for repair of cardiac valves, and particularly the mitral valve, as a therapy for regurgitation. The invention enables two or more valve leaflets to be coapted using an “edge-to-edge” or “bow-tie” technique to reduce regurgitation, yet does not require open surgery through the chest and heart wall as in conventional approaches. Using the devices, systems and methods of the invention, the mitral valve can be accessed from a remote surgical or vascular access point and the two valve leaflets may be coapted using endovascular or minimally invasive approaches. While less preferred, in some circumstances the invention may also find application in open surgical approaches as well. According to the invention, the mitral valve may be approached either from the atrial side (antegrade approach) or the ventricular side (retrograde approach), and either through blood vessels or through the heart wall.
The devices, systems and methods of the invention are centered on variety of devices which may be used individually or in a variety of combinations to form interventional systems. In preferred embodiments, the interventional system includes a multi-catheter guiding system, a delivery catheter and an interventional device. Each of these components will be discussed herein.
In an exemplary embodiment, the invention provides a fixation device having a pair of distal elements (or fixation elements), each distal element having a free end and an engagement surface for engaging the tissue, wherein the distal elements are moveable between a first position for capturing the tissue and a second position for fixing the tissue. Preferably, the engagement surfaces are spaced apart in the first position and are closer together and generally face toward each other in the second position. The fixation device is preferably delivered to a target location in a patient's body by a delivery catheter having an elongated shaft, a proximal end and a distal end, the delivery catheter being configured to be positioned at the target location from a remote access point such as a vascular puncture or cut-down or a surgical penetration. In a preferred embodiment, the target location is a valve in the heart.
The fixation device is preferably delivered with the distal elements in a delivery position configured to minimize the profile of the device. When approaching the mitral valve from the atrial side, some embodiments of the fixation device allow the device to be delivered with the free ends of the distal elements pointing in a generally proximal direction forming an angle of less than about 90°, preferably less than about 20°, relative to the longitudinal axis of the delivery device shaft. In this position the engagement surfaces are facing generally toward each other, being disposed at an angle of less than about 180°, and preferably less than about 40°, relative to each other. For ventricular approaches, in the delivery position the free ends of the distal elements are pointing in a generally distal direction and form an angle of less than about 90°, preferably less than about 20° relative to the longitudinal axis of the delivery device shaft. In this position, the engagement surfaces are facing generally toward each other, usually being disposed at an angle of less than about 180°, and preferably less than about 90°, relative to each other. Alternatively, in some ventricular approaches, it may be preferred to have the free ends of the fixation elements pointing in a generally proximal direction and the engagement surfaces facing away from each other in the delivery position.
In order to provide for the reversibility and removability of the devices and systems of the invention, the distal elements preferably are movable to an inverted position that minimizes entanglement and interferences with surrounding tissues should the device be desired to be withdrawn. In mitral repair applications, this is particularly important due to the presence of chordae tendonae, valve leaflets and other tissues with which devices may become entangled. For approaches from the atrial side of the mitral valve, in the inverted position, the free ends will be pointing in a generally distal direction relative to the catheter shaft and the engagement surfaces will be facing generally away from each other, usually being disposed at an angle of more than about 180°, and preferably more than 270°, relative to each other. For ventricular approaches to the valve, in the inverted position the free ends will be pointing in a distal direction relative to the catheter shaft and the engagement surfaces will be facing generally toward each other, usually being disposed at an angle of less than about 180°, and preferably less than 90°, relative to each other.
In the open position, the engagement surfaces of the distal elements preferably form an angle of up to 180° relative to each other so as to maximize the area in which to capture the valve leaflets or other target tissue. The distal elements are preferably movable to a closed position in which the engagement surfaces engage each other or form an angle as small as 0° relative to each other. The distal elements are configured to be adjusted to and left permanently in any of various positions between the open and closed positions to allow for fixation of tissues of various thickness, geometry, and spacing.
In a preferred embodiment, the fixation device of the invention will further include at least one proximal element (or gripping element). Each proximal element and distal element will be movable relative to each other and configured to capture tissue between the proximal element and the engagement surface of the distal element. Preferably, the distal elements and proximal elements are independently movable but in some embodiments may be movable with the same mechanism. The proximal element may be preferably biased toward the engagement surface of the fixation element to provide a compressive force against tissue captured therebetween.
In another aspect, the invention provides a fixation device for engaging tissue comprising a coupling member configured for coupling a catheter and a pair of distal elements connected to the coupling member, each distal element having an engagement surface for engaging the tissue. The distal elements are moveable between an open position wherein the distal elements extend radially outwardly facing the engagement surfaces toward a first direction, and an inverted position wherein the distal elements have rotated away from the first direction facing the engagement surfaces radially outwardly.
In a further aspect, the distal elements of the invention are adapted to receive a suture passed through the target tissue. For example, implant pledgets may be detachably mounted to the distal elements so as to be positionable against a surface of tissue engaged by the distal elements. A suture may then be passed through the tissue and implant pledget, which are supported by the distal element. The implant pledgets are then detached from the distal elements, which may be withdrawn from the site, and the suture is tensioned and secured to the target tissue. The delivery catheter, in this embodiment, will further include a movable fixation tool or penetration element for penetrating the target tissue and the implant pledget. A suture is coupled to the penetration element and preferably an anchor is attached to the suture. The penetration element is movable relative to the catheter to penetrate the target tissue and the implant pledget, bringing with it the suture and anchor. The anchor is configured to deploy into an expanded configuration so as to securely engage the implant pledget opposite the target tissue, retaining the suture therein. For the mitral valve, an implant pledget and suture may be similarly deployed in both leaflets, and the sutures secured to one another to coapt the leaflets. Thus, in this embodiment, the distal elements are used to deliver implant pledgets and secure them to the target tissue, but are not themselves deployed at the site as in other embodiments. However, following deployment of the implant pledgets and associated sutures, the distal elements must be withdrawn from the body. For this purpose, the distal elements are movable to an inverted position like the embodiments described above to facilitate withdrawing the device without interference or injury to surrounding tissues.
In some applications such as the repair of the mitral valve, the fixation device is adapted to be detached from the delivery catheter and left permanently in the patient. In such applications, it is often desirable to promote tissue growth around the fixation device. For this purpose, some or all of the components of the fixation device are preferably covered with a covering or coating to promote tissue growth. In one embodiment, a biocompatible fabric cover is positioned over the distal elements and/or the proximal elements. The cover may optionally be impregnated or coated with various therapeutic agents, including tissue growth promoters, antibiotics, anti-clotting, blood thinning, and other agents. Alternatively or in addition, some or all of the fixation element and/or covering may be comprised of a bioerodable, biodegradable or bioabsorbable material so that it may degrade or be absorbed by the body after the repaired tissues have grown together.
The distal elements and proximal elements will be configured to provide high retention force so that the fixation device remains securely fastened to the target tissue throughout the cardiac cycle. At the same time, the distal and proximal elements will be configured to minimize trauma to the tissue engaged by them. This allows the fixation device to be removed from the tissue after initial application without creating clinically significant injury to the tissue. In order to enhance retention without creating significant trauma, the proximal elements and/or the distal elements may have friction-enhancing features on their surfaces that engage the target tissue. Such friction-enhancing features may include barbs, bumps, grooves, openings, channels, surface roughening, coverings, and coatings, among others. Optionally, magnets may be present in the proximal and/or distal elements. Preferably the friction-enhancing features and the magnets will be configured to increase the retention force of the distal and proximal elements on the tissue, while not leaving significant injury or scarring if the device is removed.
The distal and proximal elements may further have a shape and flexibility to maximize retention force and minimize trauma to the target tissue. In a preferred embodiment, the engagement surfaces of the distal elements have a concave shape configured to allow the proximal elements, along with the target tissue, to be nested or recessed within the distal elements. This increases the surface area of the tissue engaged by the distal elements and creates a geometry of tissue engagement that has a higher retention force than a planar engagement surface. To minimize trauma, the longitudinal edges as well as the free ends of the distal elements are preferably curved outwardly away from the engagement surface so that these edges present a rounded surface against the target tissue. The distal elements and/or the proximal elements may also be flexible so that they deflect to some degree in response to forces against the tissue engaged thereby, reducing the chances that the tissue will tear or bruise in response to such forces.
The fixation device will include an actuation mechanism for moving the distal elements between the open, closed, and inverted positions. A variety of actuation mechanisms may be used. In an exemplary embodiment, a coupling member connects the fixation device to the delivery catheter, and a stud is slidably coupled to the coupling member. In a “push to close/pull to open” embodiment, the distal elements are pivotably coupled to the stud and the actuation mechanism comprises a pair of link members connected between the distal elements and the coupling member, whereby sliding the stud relative to the coupling member pivots the distal elements inwardly or outwardly into the various positions. Alternatively, in a “push to open/pull to close” embodiment, the distal elements are pivotably coupled to the coupling member and the links connected between the distal elements and the stud.
The fixation device of the invention preferably includes a coupling member that is detachably connectable to the delivery catheter. The coupling member may have various constructions, but in an exemplary embodiment comprises an outer member having an axial channel, the outer member being coupled to one of either the distal elements or the actuation mechanism. An inner member extends slidably through the axial channel and is coupled to the other of either the distal elements or the actuation mechanism. The delivery catheter will be configured to detachably connect to both the inner member and the outer member. In one embodiment, the delivery catheter has a tubular shaft and an actuator rod slidably disposed in the tubular shaft. The junction of the outer member with the tubular shaft comprises a joining line, which may have a variety of shapes including sigmoid curves. The actuator rod extends from the delivery catheter through the axial channel in the outer member to maintain its connection with the tubular shaft. The actuator rod may be connected to the inner member by various connection structures, including threaded connections. By detachment of the actuator rod from the inner member and retraction of the actuator rod back into the tubular shaft, the outer member is released from the tubular shaft to allow deployment of the fixation device.
In a preferred embodiment, the fixation device further includes a locking mechanism that maintains the distal elements in a selected position relative to each other. Because the ideal degree of closure of the fixation device may not be known until it is actually applied to the target tissue, the locking mechanism is configured to retain the distal elements in position regardless of how open or closed they may be. While a variety of locking mechanisms may be used, in an exemplary embodiment the locking mechanism comprises a wedging element that is movable into frictional engagement with a movable component of the fixation device to prevent further movement of the distal elements. In embodiments utilizing the actuation mechanism described above, the component with which the wedging element engages may be the coupling member or the stud slidably coupled thereto. In one embodiment, the stud passes through an aperture in the coupling member that has a sloping sidewall, and the wedging element comprises a barbell disposed between the sidewall and the stud.
The fixation device preferably also includes an unlocking mechanism for releasing the locking mechanism, allowing the distal elements and proximal elements to move. In one embodiment, the unlocking mechanism comprises a harness coupled to the wedging element of the locking mechanism to reduce frictional engagement with the movable component of the fixation device. In an exemplary embodiment, the harness is slidably coupled to the coupling member and extends around the wedging element of the locking mechanism, whereby the harness can be retracted relative to the coupling member to disengage the wedging element from the stud.
In a further aspect, the invention provides an interventional system comprising a tubular guide having a proximal end, a distal end and a channel therebetween, the distal end of the tubular guide being deflectable about a first axis; a delivery catheter positionable through the channel, the delivery catheter having a flexible shaft with a proximal end, a distal end, a lumen therebetween, and an actuation element movably disposed in the lumen; and a fixation device having a coupling member releasably coupled to the distal end of the shaft, a first distal element movably coupled to the coupling member, and a first proximal element movable relative to the distal element, the first distal element being releasably coupled to the actuation element and movable therewith, the first distal element and the first proximal element being adapted to engage tissue therebetween.
The delivery device of the invention is adapted to allow the user to deliver the fixation device to the target site from a remote access point, whether through endovascular or surgical approaches, align the device with the target tissue, and to selectively close, open, invert, lock or unlock the distal element. In some embodiments, the delivery device will have a highly flexible, kink resistant, torsionally stiff shaft with minimal elongation and high compressive strength. The delivery device will also have the movable components and associated actuators to move the distal elements between the open, closed, and inverted positions, to move the proximal elements into engagement with the target tissue, to unlock the locking mechanism, and to detach the distal element from the delivery catheter. In a preferred embodiment, the delivery device comprises a delivery catheter having an elongated shaft which has an inner lumen. The distal end of the shaft is configured for detachable connection to the coupling member of the fixation device. An actuator rod is slidably disposed in the inner lumen and is adapted for detachable coupling to the stud or other component of the fixation device that moves the distal elements. A plurality of tubular guides, preferably in the form of metallic or polymeric coils, extend through the inner lumen of the shaft and are typically fixed to the shaft near its proximal and distal ends but are unrestrained therebetween, providing a highly flexible and kink-resistant construction. Lines for actuating the proximal elements and the unlocking mechanism of the fixation device extend through these tubular guides and are detachably coupled to the proximal element and unlocking mechanisms. These and other aspects of delivery catheters suitable for use in the present invention are described in copending application Ser. No. 10/441,687, filed on the same day as the present application, which has been incorporated herein by reference.
The delivery catheter may additionally include a tether that is detachably coupled to a portion of the fixation device for purposes of retrieval of the device following detachment from the delivery catheter. The tether may be a separate flexible filament extending from the delivery catheter to the fixation device, but alternatively may be a line coupled to either the unlocking mechanism or the proximal element and used also for actuating those components. In either case, the tether will be detachable from the fixation device so that it may be detached once the device has been deployed successfully.
The system of the invention may additionally include a guide that facilitates introduction and navigation of the delivery catheter and fixation device to the target location. The guide is preferably tubular with a channel extending between its proximal and distal ends in which the delivery catheter and fixation device may be slidably positioned. The distal end of the guide is steerable, usually being deflectable about at least one axis, and preferably about two axes. The guide will have a size, material, flexibility and other characteristics suitable for the application in which it is being used. For mitral valve repair, the guide is preferably configured to be introduced in a femoral vein and advanced through the inferior vena cava into the heart, across a penetration in the interatrial septum, and into alignment with the mitral valve in the left atrium. Alternatively, the guide may be configured for introduction in a femoral, axillary, or brachiocephalic artery and advancement through the aorta and aortic valve into the ventricle where it is steered into alignment with the mitral valve. In a further alternative, the guide may be configured for introduction through a puncture or incision in the chest wall and through an incision in the wall of the heart to approach the mitral valve.
In an exemplary embodiment, the guide comprises a multi-catheter guiding system which has two components, including an inner tubular member or inner guide catheter and an outer tubular member or outer guide catheter. The inner tubular member has a distal end deflectable about a first axis. The outer tubular member has a distal end deflectable about a second axis. Further, the inner tubular member may be rotatable relative to the outer tubular member about its longitudinal axis. Mobility in additional directions and about additional axes may optionally be provided. Additional aspects of guides usable in the system of the invention are described in pending application Ser. No. 10/441,508, which has been incorporated herein by reference.
The invention further provides methods of performing therapeutic interventions at a tissue site. In one embodiment, the method includes the steps of advancing an interventional tool having a proximal end, a distal end and a fixation device near the distal end to a location within a patient's body, wherein the fixation device includes a pair of distal elements each having a free end and an engagement surface; moving the distal elements to an open position wherein the free ends are spaced apart; positioning the distal elements such that the engagement surfaces engage tissue at the tissue site; and detaching the fixation device from the interventional tool. Preferably, the method further includes the step of inverting the distal elements to an inverted position wherein the free ends point generally in a distal direction. In some embodiments, the engagement surfaces will face generally away from each other in the inverted position, while in other embodiments, the engagement surfaces will face generally toward each other in the inverted position.
In an exemplary embodiment, the tissue site comprises first and second leaflets, and the step of moving the distal elements comprises coapting the leaflets. The leaflets may be part of a variety of tissue structures, but are preferably part of a cardiac valve such as the mitral valve. In antegrade approaches, the step of advancing will usually include inserting the fixation device through a valve annulus, e.g. from an atrium of the heart to a ventricle of the heart. In such approaches, the method may further include a step of withdrawing the fixation device through the valve annulus with the fixation device in the inverted position. Retrograde approaches are also provided, in which the step of advancing will include the step of passing the fixation device through a ventricle of the heart into an atrium of the heart. The step of advancing may further comprise transluminally positioning the fixation device through a blood vessel into the heart, and may include inserting the fixation device through an interatrial septum of the heart. Alternatively, the step of advancing may comprise inserting the device through a surgical penetration in a body wall.
The method may further include moving the distal elements to a closed position after the step of positioning, the free ends of the distal element being closer together in the closed position with the engagement surfaces facing generally toward each other. In addition, the method may include a step of deploying a proximal element on the fixation device toward each engagement surface to as to capture tissue therebetween. Before the step of inverting, the proximal elements are retracted away from the engagement surfaces. The method optionally includes a step of locking the distal elements in a desired position, and may further include a step of unlocking the distal elements so that they are movable again.
In a further aspect, a method according to the invention comprises advancing a catheter having a proximal end, a distal end and a fixation device near the distal end to a location within a body, wherein the fixation device includes a pair of distal elements each having an engagement surface; moving the distal elements to an open position wherein the distal elements extend radially outwardly facing the engagement surfaces toward a direction other than radially outwardly; and moving the distal elements to an inverted position wherein the engagement surfaces face radially outwardly.
In still another aspect, the invention provides a method for fixing tissues together comprising advancing a catheter having a proximal end, a distal end and a fixation device disposed near the distal end to a location near the tissues, wherein the fixation device includes a pair of distal elements each having a removable implant pledget; moving the distal elements so that each implant pledget engages one of the tissues; penetrating each tissue and engaged implant pledget and passing a tie therethrough; fastening the ties to fix the tissues together; and removing the fixation device leaving the implant pledget in place.
In an additional aspect of the invention, kits for performing an intervention at a tissue site in a patient's body include a fixation device and Instructions for Use setting forth the steps of using the fixation device according to the methods of the invention. The fixation device may be as described in any of the various examples set forth herein. The kits may further include a delivery tool or catheter for delivering the fixation device to the tissue site, as well as a tubular guide through which the delivery tool or catheter may be positioned.
Other aspects of the nature and advantages of the invention are set forth in the detailed description set forth below, taken in conjunction with the drawings.
The left ventricle LV of a normal heart H in systole is illustrated in
A number of structural defects in the heart can cause mitral valve regurgitation. Regurgitation occurs when the valve leaflets do not close properly allowing leakage from the ventricle into the atrium. As shown in
The present invention provides methods and devices for grasping, approximating and fixating tissues such as valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. The present invention also provides features that allow repositioning and removal of the device if so desired, particularly in areas where removal may be hindered by anatomical features such as chordae CT. Such removal would allow the surgeon to reapproach the valve in a new manner if so desired.
Grasping will preferably be atraumatic providing a number of benefits. By atraumatic, it is meant that the devices and methods of the invention may be applied to the valve leaflets and then removed without causing any significant clinical impairment of leaflet structure or function. The leaflets and valve continue to function substantially the same as before the invention was applied. Thus, some minor penetration or denting of the leaflets may occur using the invention while still meeting the definition of “atraumatic”. This enables the devices of the invention to be applied to a diseased valve and, if desired, removed or repositioned without having negatively affected valve function. In addition, it will be understood that in some cases it may be necessary or desirable to pierce or otherwise permanently affect the leaflets during either grasping, fixing or both. In some of these cases, grasping and fixation may be accomplished by a single device. Although a number of embodiments are provided to achieve these results, a general overview of the basic features will be presented herein. Such features are not intended to limit the scope of the invention and are presented with the aim of providing a basis for descriptions of individual embodiments presented later in the application.
The devices and methods of the invention rely upon the use of an interventional tool that is positioned near a desired treatment site and used to grasp the target tissue. In endovascular applications, the interventional tool is typically an interventional catheter. In surgical applications, the interventional tool is typically an interventional instrument. In preferred embodiments, fixation of the grasped tissue is accomplished by maintaining grasping with a portion of the interventional tool which is left behind as an implant. While the invention may have a variety of applications for tissue approximation and fixation throughout the body, it is particularly well adapted for the repair of valves, especially cardiac valves such as the mitral valve. Referring to
The fixation device 14 is releasably attached to the shaft 12 of the interventional tool 10 at its distal end. When describing the devices of the invention herein, “proximal” shall mean the direction toward the end of the device to be manipulated by the user outside the patient's body, and “distal” shall mean the direction toward the working end of the device that is positioned at the treatment site and away from the user. With respect to the mitral valve, proximal shall refer to the atrial or upstream side of the valve leaflets and distal shall refer to the ventricular or downstream side of the valve leaflets.
The fixation device 14 typically comprises proximal elements 16 (or gripping elements) and distal elements 18 (or fixation elements) which protrude radially outward and are positionable on opposite sides of the leaflets LF as shown so as to capture or retain the leaflets therebetween. The proximal elements 16 are preferably comprised of cobalt chromium, nitinol or stainless steel, and the distal elements 18 are preferably comprised of cobalt chromium or stainless steel, however any suitable materials may be used. The fixation device 14 is coupleable to the shaft 12 by a coupling mechanism 17. The coupling mechanism 17 allows the fixation device 14 to detach and be left behind as an implant to hold the leaflets together in the coapted position.
In some situations, it may be desired to reposition or remove the fixation device 14 after the proximal elements 16, distal elements 18, or both have been deployed to capture the leaflets LF. Such repositioning or removal may be desired for a variety of reasons, such as to reapproach the valve in an attempt to achieve better valve function, more optimal positioning of the device 14 on the leaflets, better purchase on the leaflets, to detangle the device 14 from surrounding tissue such as chordae, to exchange the device 14 with one having a different design, or to abort the fixation procedure, to name a few. To facilitate repositioning or removal of the fixation device 14 the distal elements 18 are releasable and optionally invertible to a configuration suitable for withdrawal of the device 14 from the valve without tangling or interfering with or damaging the chordae, leaflets or other tissue.
Once the leaflets are coapted in the desired arrangement, the fixation device 14 is then detached from the shaft 12 and left behind as an implant to hold the leaflets together in the coapted position. As mentioned previously, the fixation device 14 is coupled to the shaft 12 by a coupling mechanism 17.
Similarly,
In a preferred embodiment, mating surface 24 (or mating surface 32) is a sigmoid curve defining a male element and female element on upper shaft 20 (or upper shaft 28) which interlock respectively with corresponding female and male elements on lower shaft 22 (or lower shaft 30). Typically, the lower shaft is the coupling mechanism 17 of the fixation device 14. Therefore, the shape of the mating surface selected will preferably provide at least some mating surfaces transverse to the axial axis of the a mechanism 19 to facilitate application of compressive and tensile forces through the coupling mechanism 17 to the fixation device 14, yet causing minimal interference when the fixation device 14 is to be released from the upper shaft.
A. Introduction and Placement of Fixation Device
The fixation device 14 is delivered to the valve or the desired tissues with the use of a delivery device. The delivery device may be rigid or flexible depending on the application. For endovascular applications, the delivery device comprises a flexible delivery catheter which will be described in later sections. Typically, however, such a catheter comprises a shaft, having a proximal end and a distal end, and a fixation device releasably attached to its distal end. The shaft is usually elongate and flexible, suitable for intravascular introduction. Alternatively, the delivery device may comprise a shorter and less flexible interventional instrument which may be used for trans-thoracic surgical introduction through the wall of the heart, although some flexibility and a minimal profile will generally be desirable. A fixation device is releasably coupleable with the delivery device as illustrated in
In this embodiment, proximal elements 16 comprise resilient loop-shaped wire forms biased outwardly and attached to the coupling member 19 so as to be biased to an open position shown in
In some situations, as previously mentioned, it may be desirable to reopen the fixation device 14 following initial placement. To reopen the device 14, the actuator rod may be readvanced or reinserted through the coupling member 19 and readvanced to press against the actuation mechanism 58, as previously indicated by arrow 62 in
Under some circumstances, it may be further desirable to withdraw the fixation device 14 back through the valve or completely from the patient following initial insertion through the valve. Should this be attempted with the clip in the closed or open positions illustrated in
With arms 53 in the inverted position, engagement surfaces 50 provide an atraumatic surface deflect tissues as the fixation device is withdrawn. This allows the device to be retracted back through the valve annulus without risk of injury to valvular and other tissues. In some cases, once the fixation device 14 has been pulled back through the valve, it will be desirable to return the device to the closed position for withdrawal of the device from the body (either through the vasculature or through a surgical opening).
The embodiment illustrated in
In a further embodiment, some or all of the components may be molded as one part, as illustrated in
In a preferred embodiment suitable for mitral valve repair, the transverse width across engagement surfaces 50 (which determines the width of tissue engaged) is at least about 2 mm, usually 3-10 mm, and preferably about 4-6 mm. In some situations, a wider engagement is desired wherein the engagement surfaces 50 are larger, for example about 2 cm, or multiple fixation devices are used adjacent to each other. Arms 53 and engagement surfaces 50 are configured to engage a length of tissue of about 4-10 mm, and preferably about 6-8 mm along the longitudinal axis of arms 53. Arms 53 further include a plurality of openings to enhance grip and to promote tissue ingrowth following implantation.
The valve leaflets are grasped between the distal elements 18 and proximal elements 16. In some embodiments, the proximal elements 16 are flexible, resilient, and cantilevered from coupling member 19. The proximal elements are preferably resiliently biased toward the distal elements. Each proximal element 16 is shaped and positioned to be at least partially recessed within the concavity of the distal element 18 when no tissue is present. When the fixation device 14 is in the open position, the proximal elements 16 are shaped such that each proximal element 16 is separated from the engagement surface 50 near the proximal end 52 of arm 53 and slopes toward the engagement surface 50 near the free end 54 with the free end of the proximal element contacting engagement surface 50, as illustrated in
Proximal elements 16 include a plurality of openings 63 and scalloped side edges 61 to increase grip on tissue. The proximal elements 16 optionally include frictional accessories, frictional features or grip-enhancing elements to assist in grasping and/or holding the leaflets. In preferred embodiments, the frictional accessories comprise barbs 60 having tapering pointed tips extending toward engagement surfaces 50. It may be appreciated that any suitable frictional accessories may be used, such as prongs, windings, bands, barbs, grooves, channels, bumps, surface roughening, sintering, high-friction pads, coverings, coatings or a combination of these. Optionally, magnets may be present in the proximal and/or distal elements. It may be appreciated that the mating surfaces will be made from or will include material of opposite magnetic charge to cause attraction by magnetic force. For example, the proximal elements and distal elements may each include magnetic material of opposite charge so that tissue is held under constant compression between the proximal and distal elements to facilitate faster healing and ingrowth of tissue. Also, the magnetic force may be used to draw the proximal elements 16 toward the distal elements 18, in addition to or alternatively to biasing of the proximal elements toward the distal elements. This may assist in deployment of the proximal elements 16. In another example, the distal elements 18 each include magnetic material of opposite charge so that tissue positioned between the distal elements 18 is held therebetween by magnetic force.
The proximal elements 16 may be covered with a fabric or other flexible material as described below to enhance grip and tissue ingrowth following implantation. Preferably, when fabrics or coverings are used in combination with barbs or other frictional features, such features will protrude through such fabric or other covering so as to contact any tissue engaged by proximal elements 16.
In an exemplary embodiment, proximal elements 16 are formed from metallic sheet of a spring-like material using a stamping operation which creates openings 63, scalloped edges 61 and barbs 60. Alternatively, proximal elements 16 could be comprised of a spring-like material or molded from a biocompatible polymer. It should be noted that while some types of frictional accessories that can be used in the present invention may permanently alter or cause some trauma to the tissue engaged thereby, in a preferred embodiment, the frictional accessories will be atraumatic and will not injure or otherwise affect the tissue in a clinically significant way. For example, in the case of barbs 60, it has been demonstrated that following engagement of mitral valve leaflets by fixation device 14, should the device later be removed during the procedure barbs 60 leave no significant permanent scarring or other impairment of the leaflet tissue and are thus considered atraumatic.
The fixation device 14 also includes an actuation mechanism 58. In this embodiment, the actuation mechanism 58 comprises two link members or legs 68, each leg 68 having a first end 70 which is rotatably joined with one of the distal elements 18 at a riveted joint 76 and a second end 72 which is rotatably joined with a stud 74. The legs 68 are preferably comprised of a rigid or semi-rigid metal or polymer such as Elgiloy®, cobalt chromium or stainless steel, however any suitable material may be used. While in the embodiment illustrated both legs 68 are pinned to stud 74 by a single rivet 78, it may be appreciated, however, that each leg 68 may be individually attached to the stud 74 by a separate rivet or pin. The stud 74 is joinable with an actuator rod 64 (not shown) which extends through the shaft 12 and is axially extendable and retractable to move the stud 74 and therefore the legs 68 which rotate the distal elements 18 between closed, open and inverted positions. Likewise, immobilization of the stud 74 holds the legs 68 in place and therefore holds the distal elements 18 in a desired position. The stud 74 may also be locked in place by a locking feature which will be further described in later sections.
In any of the embodiments of fixation device 14 disclosed herein, it may be desirable to provide some mobility or flexibility in distal elements 18 and/or proximal elements 16 in the closed position to enable these elements to move or flex with the opening or closing of the valve leaflets. This provides shock absorption and thereby reduces force on the leaflets and minimizes the possibility for tearing or other trauma to the leaflets. Such mobility or flexibility may be provided by using a flexible, resilient metal or polymer of appropriate thickness to construct the distal elements 18. Also, the locking mechanism of the fixation device (described below) may be constructed of flexible materials to allow some slight movement of the proximal and distal elements even when locked. Further, the distal elements 18 can be connected to the coupling mechanism 19 or to actuation mechanism 58 by a mechanism that biases the distal element into the closed position (inwardly) but permits the arms to open slightly in response to forces exerted by the leaflets. For example, rather than being pinned at a single point, these components may be pinned through a slot that allowed a small amount of translation of the pin in response to forces against the arms. A spring is used to bias the pinned component toward one end of the slot.
Proximal elements 16 are typically biased outwardly toward arms 53. The proximal elements 16 may be moved inwardly toward the shaft 12 and held against the shaft 12 with the aid of proximal element lines 90 which can be in the form of sutures, wires, nitinol wire, rods, cables, polymeric lines, or other suitable structures. The proximal element lines 90 may be connected with the proximal elements 16 by threading the lines 90 in a variety of ways. When the proximal elements 16 have a loop shape, as shown in
In the open position, the fixation device 14 can engage the tissue which is to be approximated or treated. The embodiment illustrated in
The interventional tool 10 may be repeatedly manipulated to reposition the fixation device 14 so that the leaflets are properly contacted or grasped at a desired location. Repositioning is achieved with the fixation device in the open position. In some instances, regurgitation may also be checked while the device 14 is in the open position. If regurgitation is not satisfactorily reduced, the device may be repositioned and regurgitation checked again until the desired results are achieved.
It may also be desired to invert the fixation device 14 to aid in repositioning or removal of the fixation device 14.
Once the fixation device 14 has been positioned in a desired location against the valve leaflets, the leaflets may then be captured between the proximal elements 16 and the distal elements 18.
After the leaflets have been captured between the proximal and distal elements 16, 18 in a desired arrangement, the distal elements 18 may be locked to hold the leaflets in this position or the fixation device 14 may be returned to or toward a closed position. Such locking will be described in a later section.
As shown in
In an exemplary embodiments, proximal element lines 90 are elongated flexible threads, wire, cable, sutures or lines extending through shaft 12, looped through proximal elements 16, and extending back through shaft 12 to its proximal end. When detachment is desired, one end of each line may be released at the proximal end of the shaft 12 and the other end pulled to draw the free end of the line distally through shaft 12 and through proximal element 16 thereby releasing the fixation device.
While the above described embodiments of the invention utilize a push-to-open, pull-to-close mechanism for opening and closing distal elements 18, it should be understood that a pull-to-open, push-to-close mechanism is equally possible. For example, distal elements 18 may be coupled at their proximal ends to stud 74 rather than to coupling member 19, and legs 68 may be coupled at their proximal ends to coupling member 19 rather than to stud 74. In this example, when stud 74 is pushed distally relative to coupling member 19, distal elements 18 would close, while pulling on stud 74 proximally toward coupling member 19 would open distal elements 18.
B. Covering on Fixation Device
The fixation device 14 may optionally include a covering. The covering may assist in grasping the tissue and may later provide a surface for tissue ingrowth. Ingrowth of the surrounding tissues, such as the valve leaflets, provides stability to the device 14 as it is further anchored in place and may cover the device with native tissue thus reducing the possibility of immunologic reactions. The covering may be comprised of any biocompatible material, such as polyethylene terepthalate, polyester, cotton, polyurethane, expanded polytetrafluoroethylene (ePTFE), silicon, or various polymers or fibers and have any suitable form, such as a fabric, mesh, textured weave, felt, looped or porous structure. Generally, the covering has a low profile so as not to interfere with delivery through an introducer sheath or with grasping and coapting of leaflets or tissue.
The covering 100 may alternatively be comprised of a polymer or other suitable materials dipped, sprayed, coated or otherwise adhered to the surfaces of the fixation device 14. Optionally, the polymer coating may include pores or contours to assist in grasping the tissue and/or to promote tissue ingrowth.
Any of the coverings 100 may optionally include drugs, antibiotics, anti-thrombosis agents, or anti-platelet agents such as heparin, COUMADIN® (Warfarin Sodium), to name a few. These agents may, for example, be impregnated in or coated on the coverings 100. These agents may then be delivered to the grasped tissues surrounding tissues and/or bloodstream for therapeutic effects.
C. Fixation Device Locking Mechanisms
As mentioned previously, the fixation device 14 optionally includes a locking mechanism for locking the device 14 in a particular position, such as an open, closed or inverted position or any position therebetween. It may be appreciated that the locking mechanism includes an unlocking mechanism which allows the device to be both locked and unlocked.
The locking mechanism 106 allows the fixation device 14 to remain in an unlocked position when attached to the interventional tool 10 during grasping and repositioning and then maintain a locked position when left behind as an implant. It may be appreciated, however, that the locking mechanism 106 may be repeatedly locked and unlocked throughout the placement of the fixation device 14 if desired. Once the final placement is determined, the lock line 92 and proximal element lines 90 are removed and the fixation device is left behind.
Deployment of the proximal elements 16, as shown in
D. Additional Embodiments of Fixation Devices
In use, the embodiment of
In a further alternative of the embodiment of
Optionally, the fixation device 14 may include tissue retention features such as barbs 170 and/or bumpers 172, illustrated in
It may be appreciated that when the fixation device 14 is mounted on the shaft 12 in orientation illustrated in
In the open position, tissue or leaflets may be grasped between the distal elements 18 and proximal elements 16.
To attach the implant pledgets 210 to the leaflets, the leaflets and implant pledgets 210 are punctured by fixation tools 220, as shown in
Referring now to
The implant pledgets 210 are then separated from the fixation device 14 and left behind to maintain coaptation of the leaflets in the desired position.
It may be appreciated that the foregoing embodiment may also include proximal elements 16 configured to be positioned on the upstream side of the valve leaflets to assist in the capture and fixation. Such proximal elements may be mounted to shaft 12 so as to be removed following fixation of the leaflets, or the proximal elements may be connected to distal elements 18 and/or retention clip 36 to be implanted therewith.
In further embodiments, the proximal elements may be manipulated to enhance gripping. For example, the proximal elements may be lowered to grasp leaflets or tissue between the proximal and distal elements, and then the proximal elements may be moved to drag the leaflets or tissue into the fixation device. In another example, the proximal elements may be independently lowered to grasp the leaflets or tissue. This may be useful for sequential grasping. In sequential grasping, one proximal element is lowered to capture a leaflet or tissue portion between the proximal and distal elements. The fixation device is then moved, adjusted or maneuvered to a position for grasping another leaflet or tissue portion between another set of proximal and distal elements. In this position, the second proximal element is then lowered to grasp this other leaflet or tissue portion.

B. Delivery Catheter Shaft
Passing through the support coil 346 are a variety of elongated bodies, including tubular guides and cylindrical rods. For example, one type of tubular guide is a compression coil 326 extending through lumen 348 from the proximal end 322 to the distal end 324 of the shaft 302, and the actuator rod 64 extends through the compression coil 326. Therefore, the compression coil typically has a length in the range of 48 to 60 in. and an inner diameter in the range of 0.020 to 0.035 in. to allow passage of the actuator rod 64 therethrough. The actuator rod 64 is manipulable to rotate and translate within and relative to the compression coil 326. The compression coil 326 allows lateral flexibility of the actuator rod 64 and therefore the shaft 302 while resisting buckling and providing column strength under compression. The compression coil may be comprised of 304V stainless steel to provide these properties.
To provide additional tensile strength for the shaft 302 and to minimize elongation, a tension cable 344 may also pass through the support coil 346. The tension cable 344 extends through lumen 348 from the proximal end 322 to the distal end 324 of the shaft 302. Therefore, the tension cable 344 typically has a diameter in the range of 0.005 in. to 0.010 in. and a length in the range of 48 to 60 in. In preferred embodiments, the tension cable 344 is comprised of 304V stainless steel.
In addition, at least one lock line shaft 341 having a tubular shape may be present having a lock line lumen 340 through which lock lines 92 pass between the lock line handle 310 and the locking mechanism 106. The lock line shaft 341 extends through lumen 348 from the proximal end 322 to the distal end 324 of the shaft 302. Therefore, the lock line shaft 341 typically has a length in the range of 48 to 60 in., an inner diameter in the range of 0.016 to 0.030 in., and an outer diameter in the range of 0.018 to 0.034 in. In preferred embodiments, the lock line shaft 341 is comprised of a 304V stainless steel coil however other structures or materials may be used which provide kink resistance and compression strength.
Similarly, at least one proximal element line shaft 343 having a tubular shape may be present having a proximal element line lumen 342. Proximal element lines 90 pass through this lumen 342 between the proximal element line handle 312 and the proximal elements 16. Thus, the proximal element line shaft 343 extends through lumen 348 from the proximal end 322 to the distal end 324 of the shaft 302. Therefore, the proximal element line shaft 343 typically has a length in the range of 48 to 60 in., an inner diameter in the range of 0.016 to 0.030 in., and an outer diameter in the range of 0.018 to 0.034 in. In preferred embodiments, the proximal element line shaft 343 is comprised of a 304V stainless steel coil however other structures or materials may be used which provide kink resistance and compression strength.
In this embodiment, the elongated bodies (compression coil 326 enclosed actuator rod 64, tension cable 344, lock line shaft 342, proximal element line shaft 343) each “float” freely in inner lumen 348 within the support coil 346 and are fixed only at the proximal end 322 and distal end 324 of shaft 302. The lumen 348 is typically filled and flushed with heparinized saline during use. Alternatively or in addition, the lumen 348 may be filled with one or more fillers, such as flexible rods, beads, extruded sections, gels or other fluids. Preferably the fillers allow for some lateral movement or deflection of the elongated bodies within lumen 348 but in some cases may restrict such movement. Typically, the elongated bodies are fixed at the proximal and distal ends of the shaft and are free to move laterally and rotationally therebetween. Such freedom of movement of the elongated bodies provides the shaft 302 with an increased flexibility as the elongated bodies self-adjust and reposition during bending and/or torqueing of the shaft 302. It may be appreciated that the elongated bodies may not be fixed at the proximal and distal ends. The elongated bodies are simply unconstrained relative to the shaft 302 in at least one location so as to be laterally moveable within the lumen 348. Preferably the elongated bodies are unrestrained in at least a distal portion of the catheter, e.g. 5-15 cm from the distal end 324, so as to provide maximum flexibility in the distal portion.
It may be appreciated, however, that alternate shaft 302 designs may also be used. For example, referring to
Alternatively, as shown in
C. Lock Line Arrangements
As mentioned previously, when lock lines 92 are present, the lines 92 pass through at least one lock line lumen 340 between the lock line handle 310 and the locking mechanism 106. The lock lines 92 engage the release harnesses 108 of the locking mechanism 106 to lock and unlock the locking mechanism 106 as previously described. The lock lines 92 may engage the release harnesses 108 in various arrangements, examples of which are illustrated in
It may be appreciated that a variety of lock line arrangements may be used and are not limited to the arrangements illustrated and described above. The various arrangements allow the harnesses 108 to be manipulated independently or jointly, allow various amounts of tension to be applied and vary the force required for removal of the lock lines when the fixation device is to be left behind. For example, a single lock line passing through one or two lumens may be connected to both release harnesses for simultaneous application of tension.
D. Proximal Element Line Arrangements
As mentioned previously, when proximal element lines 90 are present, the lines 90 pass through at least one proximal element line lumen 342 between the proximal element line handle 312 and at least one proximal element 16. The proximal element lines 90 engage the proximal elements 16 to raise or lower the element 16 as previously described. The proximal element lines 90 may engage the proximal elements 16 in various arrangements, examples of which are illustrated in
It may be appreciated that a variety of proximal element line arrangements may be used and are not limited to the arrangements illustrated and described above. The various arrangements allow the proximal elements to be manipulated independently or jointly, allow various amounts of tension to be applied and vary the force required for removal of the proximal element lines when the fixation device is to be left behind. For example, a single proximal element line passing through one or two lumens in shaft 302 may be used for simultaneous actuation of both proximal elements.
E. Main Body of Handle
F. Lock Line Handle and Proximal Element Line Handle
As mentioned previously, the lock lines 92 may be may be extended, retracted, loaded with various amounts of tension or removed using the lock line handle 310. Likewise, the proximal element lines 90 may be extended, retracted, loaded with various amounts of tension or removed using the proximal element line handle 312. Both of these handles 310, 312 may be similarly designed to manipulate the appropriate lines 90, 92 passing therethrough.
Disposed near the distal end 384 of the handle 310 is at least one wing 392. In the embodiment of
The portion of the wings 392 parallel to the elongate shaft 383 have grooves or serrations 394. The serrations 394 are used to apply tension to the lock lines 92. As shown in
To remove the lock lines 92, the cap 388 is removed from the threaded nub 390 exposing the free ends of the lock lines 92. If one lock line 92 is present having two free ends, continuous pulling on one of the free ends draws the entire length of lock line 92 out of the catheter 300. If more than one lock line 92 is present, each lock line 92 will have two free ends. Continuous pulling on one of the free ends of each lock line 92 draws the entire length of each lock line 92 out of the catheter 300.
It may be appreciated that the proximal element line handle 312 has corresponding features to the lock line handle 310 and operates in the same manner as illustrated in
G. Actuator Rod Control and Handle
The actuator rod 64 may be manipulated using the actuator rod control 314 and the actuator rod handle 316.

Depending on the application, the location of the target site, and the approach selected, the devices of the invention may be modified in ways well known to those of skill in the art or used in conjunction with other devices that are known in the art. For example, the delivery catheter may be modified in length, stiffness, shape and steerability for a desired application. Likewise, the orientation of the fixation device relative to the delivery catheter may be reversed or otherwise changed. The actuation mechanisms may be changed to be driven in alternate directions (push to open, pull to close, or pull to open, push to close). Materials and designs may be changed to be, for example, more flexible or more rigid. And, the fixation device components may be altered to those of different size or shape. Further, the delivery catheter of the present invention may be used to deliver other types of devices, particularly endovascular and minimally invasive surgical devices used in angioplasty, atherectomy, stent-delivery, embolic filtration and removal, septal defect repair, tissue approximation and repair, vascular clamping and ligation, suturing, aneurysm repair, vascular occlusion, and electrophysiological mapping and ablation, to name a few. Thus, the delivery catheter of the present invention may be used for applications in which a highly flexible, kink-resistant device is desirable with high compressive, tensile and torsional strength.
A. Overview of Guiding System
Referring to
The outer guide catheter 1000 and/or the inner guide catheter 1020 are precurved and/or have steering mechanisms, embodiments of which will be described later in detail, to position the distal ends 1016, 1026 in desired directions. Precurvature or steering of the outer guide catheter 1000 directs the distal end 1016 in a first direction to create a primary curve while precurvature and/or steering of the inner guide catheter 1020 directs distal end 1026 in a second direction, differing from the first, to create a secondary curve. Together, the primary and secondary curves form a compound curve. Advancement of the interventional catheter 1030 through the coaxial guide catheters 1000, 1020 guides the interventional catheter 1030 through the compound curve toward a desired direction, usually in a direction which will allow the interventional catheter 1030 to reach its target.
Steering of the outer guide catheter 1000 and inner guide catheter 1020 may be achieved by actuation of one or more steering mechanisms. Actuation of the steering mechanisms is achieved with the use of actuators which are typically located on handles connected with each of the catheters 1000, 1020. As illustrated in
In addition, locking actuators 1058, 1060 may be used to actuate locking mechanisms to lock the catheters 1000, 1020 in a particular position. Actuators 1050, 1052, 1058, 1060 are illustrated as buttons, however it may be appreciated that these and any additional actuators located on the handles 1056, 1057 may have any suitable form including knobs, thumbwheels, levers, switches, toggles, sensors or other devices. Other embodiments of the handles will be described in detail in a later section.
In addition, the handle 1056 may include a numerical or graphical display 1061 of information such as data indicating the position the catheters 1000, 1020, or force on actuators. It may also be appreciated that actuators 1050, 1052, 1058, 1060 and any other buttons or screens may be disposed on a single handle which connects with both the catheters 1000, 1020.
B. Example Positions
Referring to
Referring now to
Similarly,
In addition, the outer guide catheter 1000 may be pre-formed and/or steerable to provide additional curves or shapes. For example, as illustrated in
The articulated position of the multi-catheter guiding system 1 illustrated in
Referring to
Referring to
In some instances, it is desired to raise or lower the distal end 1026 so that it is at a desired height in relation to the mitral valve MV. This may be accomplished by precurvature and/or by steering of the outer guide catheter 1000 to form additional curve 1110. Generally this is used to lift the distal end 1026 above the mitral MV wherein such lifting was illustrated in
When the curvatures in the catheters 1000, 1020 are formed by steering mechanisms, the steering mechanisms may be locked in place by a locking feature. Locking can provide additional stiffness and stability in the guiding system 1 for the passage of interventional devices or catheters 1030 therethrough, as illustrated in
C. Steering Mechanisms
As described previously, the curvatures may be formed in the catheters 1000, 1020 by precurving, steering or any suitable means. Precurving involves setting a specific curvature in the catheter prior to usage, such as by heat setting a polymer or by utilizing a shape-memory alloy. Since the catheters are generally flexible, loading of the catheter on a guidewire, dilator obturator or other introductory device straightens the catheter throughout the curved region. Once the catheter is positioned in the anatomy, the introductory device is removed and the catheter is allowed to relax back into the precurved setting.
To provide a higher degree of control and variety of possible curvatures, steering mechanisms may be used to create the curvatures and position the catheters. In some embodiments, the steering mechanisms comprise cables or pullwires within the wall of the catheter. As shown in
Such pullwires 1120 and/or pullwires 1120′ and associated lumens may be placed in any arrangement, singly or in pairs, symmetrically or nonsymmetrically and any number of pullwires may be present. This may allow curvature in any direction and about various axes. The pullwires 1120, 1120′ may be fixed at any location along the length of the catheter by any suitable method, such as gluing, tying, soldering, or potting, to name a few. When tension is applied to the pullwire, the curvature forms from the point of attachment of the pullwire toward the proximal direction. Therefore, curvatures may be formed throughout the length of the catheter depending upon the locations of the points of attachment of the pullwires. Typically, however, the pullwires will be attached near the distal end of the catheter, optionally to an embedded tip ring 280, illustrated in
D. Catheter Construction
The outer guide catheter 1000 and inner guide catheter 1020 may have the same or different construction which may include any suitable material or combination of materials to create the above described curvatures. For clarity, the examples provided will be in reference to the outer guide catheter 1000, however it may be appreciated that such examples may also apply to the inner guide catheter 1020.
In embodiments in which the catheter is precurved rather than steerable or in addition to being steerable, the catheter 1000 may be comprised of a polymer or copolymer which is able to be set in a desired curvature, such as by heat setting. Likewise, the catheter 1000 may be comprised of a shape-memory alloy.
In embodiments in which the catheter is steerable, the catheter 1000 may be comprised of one or more of a variety of materials, either along the length of the catheter 1000 or in various segments. Example materials include polyurethane, Pebax, nylon, polyester, polyethylene, polyimide, polyethylenetelephthalate (PET), polyetheretherketone (PEEK). In addition, the walls of the catheter 1000 may be reinforced with a variety of structures, such as metal braids or coils. Such reinforcements may be along the length of the catheter 1000 or in various segments.
For example, referring to
Thus, the keying feature may be present along one or more specific portions of the catheters 1000, 1020 or may extend along the entire length of the catheters 1000, 1020. Likewise, the notches 1402 may extend along the entire length of the outer guiding catheter 1020 while the protrusions 1400 extend along discrete portions of the inner guiding catheter 1000 and vice versa. It may further be appreciated that the protrusions 1400 may be present on the inner surface of the outer guiding catheter 1000 while the notches 1402 are present along the outer surface of the inner guiding catheter 1020.
Alternatively or in addition, one or more steerable portions of the catheter 1000 may comprise a series of articulating members 1180 as illustrated in
Briefly, referring to
The interfitting domed rings 1184 are connected by at least one pullwire 1120. Such pullwires typically extend through the length of the catheter 1000 and at least one of the interfitting domed rings 1184 to a fixation point where the pullwire 1120 is fixedly attached. By applying tension to the pullwire 1120, the pullwire 1120 arcs the series of interfitting domed rings 1184 proximal to the attachment point to form a curve. Thus, pulling or applying tension on at least one pullwire, steers or deflects the catheter 1000 in the direction of that pullwire 1120. By positioning various pullwires 1120 throughout the circumference of the domed rings 1184, the catheter 1000 may be directed in any number of directions.

E. Handles
As mentioned previously, manipulation of the guide catheters 1000, 1020 is achieved with the use of handles 1056, 1057 attached to the proximal ends of the catheters 1000, 1020.
Each handle 1056, 1057 includes two steering knobs 1300a, 1300b emerging from a handle housing 1302 for manipulation by a user. Steering knobs 1300a are disposed on a side of the housing 1302 and steering knobs 1300b are disposed on a face of the housing 1302. However, it may be appreciated that such placement may vary based on a variety of factors including type of steering mechanism, size and shape of handle, type and arrangement of parts within handle, and ergonomics to name a few.
The knob gear wheel 1310 is a toothed wheel that engages a disk gear wheel 1312. Rotation of the steering knob 1300a rotates the knob post 1318 and knob gear wheel 1310 which in turn rotates the disk gear wheel 1312. Rotation of the disk gear wheel 1312 applies tension to one or more pullwires extending through the attached catheter, in this example the outer guiding catheter 1000. As shown, the outer guiding catheter 1000 passes through the base 1308, wherein one or more pullwires 1120 extending through the catheter 1000 are attached to the disk 1314. Such attachment is schematically illustrated in
In some instances, it is desired to restrict rotation of the disk 1314 to a degree of rotation which is more than 360 degrees. This may be achieved with another embodiment of the hard stop gear assembly 1304. Referring now to
Referring now to
It may be appreciated that one or more pullwires 1120 are attached to the disk 1314 in a manner similar to that illustrated in
As mentioned, each steering mechanism includes at least a hard stop gear assembly 1304 and a friction assembly 1306. As described above, tension is applied to one or more pullwires by action of the hard stop gear assembly to form a curve in a catheter. Tension is maintained by the friction assembly.
The steering knob 1300b and knob post 1318 are held in a rotated position by friction provided by a frictional pad 1370. The frictional pad 1370 is positioned between ring 1372 attached to the knob post 1318 and a plate 1374 attached to the base 1308. The knob post 1318 extends from the knob 1300b through the ring 1372, the frictional pad 1370 and then the plate 1374. The plate 1374 has internal threads which mate with threads on the knob post 1318. As the knob post 1318 rotates, the threads on the post 1318 advance through the threads on the plate 1374. This draws the ring 1372 closer to the plate 1374, compressing the frictional pad 1370 therebetween. Frictional pad 1370 may be comprised of any O-ring or sheet material with desirable frictional and compressibility characteristics, such as silicone rubber, natural rubber or synthetic rubbers, to name a few. In preferred embodiments, an EPDM rubber O-ring is used. Reverse rotation of the knob post 1318 is resisted by friction of the frictional pad 1370 against the ring 1372. The higher the compression of the frictional pad 1370 the stronger the frictional hold. Therefore, as the steering knob 1300b is rotated and increasing amounts of tension are applied to the pullwires 1120, increasing amounts of friction are applied to the ring 1372 to hold the knob 1300b in place.
Manual reverse rotation of the steering knob 1300b releases tension on the pullwires 1120 and draws the ring 1372 away from the plate 1374 thereby reducing the frictional load. When tension is released from the pullwires 1120 the catheter 1000 returns toward a straightened position.
It may be appreciated that each handle 1056, 1057 includes a steering mechanism for each curve to be formed in the attached catheter. Thus, as shown in
Some curves, such as the primary curve 1100, secondary curve 1104 and additional curve 1110 each typically vary in curvature between a straight configuration and a curved configuration in a single direction. Such movement may be achieved with single set of a hard stop gear assembly 1304 and a friction assembly 1306. However, other curves, such as the angle theta 1070, may be formed in two directions as shown in
It may be appreciated that various other mechanisms may be used for tensioning and holding pullwires 1120 in place. Example mechanisms that may alternatively be used include clutches, ratchets, levers, knobs, rack and pinions, and deformable handles, to name a few.
F. Interventional System
To assist in inserting the fixation device 14 through a hemostatic valve 1090, a fixation device introducer may be used. For example, when the fixation device 14 is loaded on a delivery catheter 300 and an inner guide catheter 1020, insertion of the fixation device 14, delivery catheter 300 and inner guide catheter 1020 through an outer guide catheter 1000 involves passing the fixation device 14 through a hemostatic valve 1090 on the outer guide catheter 1000. To reduce any trauma to the fixation device 14 by the hemostatic valve 1090, a fixation device introducer may be used. An embodiment of a fixation device introducer 1420 is illustrated in
Manipulation of the guide catheters 1000, 1020 is achieved with the use of handles 1056, 1057 attached to the proximal ends of the catheters 1000, 1020. As shown, handle 1056 is attached to the proximal end 1014 of outer guide catheter 1000 and handle 1057 is attached to the proximal end 1024 of inner guide catheter 1020. Inner guide catheter 1020 is inserted through handle 1056 and is positioned coaxially within outer guide catheter 1000.
An embodiment of the delivery catheter 300 of the present invention is inserted through handle 1057 and is positioned coaxially within inner guide catheter 1020 and outer guide catheter 1000. Therefore, a hemostatic valve 1090 is disposed within handle 1057 or external to handle 1057 as shown to provide leak-free sealing with or without the delivery catheter 300 in place. The valve 1090 functions as described above. The delivery catheter 300 includes a shaft 302, having a proximal end 322 and a distal end 324, and a handle 304 attached to the proximal end 322. A fixation device 14 is removably coupled to the distal end 324 for delivery to a site within the body.
The outer guide catheter 1000 and/or the inner guide catheter 1020 are precurved and/or have steering mechanisms to position the distal ends 1016, 1026 in desired directions. Precurvature or steering of the outer guide catheter 1000 directs the distal end 1016 in a first direction to create a primary curve while precurvature and/or steering of the inner guide catheter 1020 directs distal end 1026 in a second direction, differing from the first, to create a secondary curve. Together, the primary and secondary curves form a compound curve. Advancement of the delivery catheter 300 through the coaxial guide catheters 1000, 1020 guides the delivery catheter 300 through the compound curve toward a desired direction, usually in a direction which will position the fixation device 14 in a desired location within the body.
It may be appreciated the above described systems 3 are not intended to limit the scope of the present invention. The systems 3 may include any or all of the components of the described invention. In addition, the multi-catheter guiding system 1 of the present invention may be used to introduce other delivery catheters, interventional catheters or other devices. Likewise, the delivery catheter 300 may be introduced through other introducers or guiding systems. Also, the delivery catheter 300 may be used to deliver other types of devices to a target location within the body, including endoscopic staplers, devices for electrophysiology mapping or ablation, septal defect repair devices, heart valves, annuloplasty rings and others.
In addition, many of the components of the system 3 may include one or more hydrophilic coatings. Hydrophilic coatings become slippery when wet, eliminate the need for separate lubricants. Thus, such coatings may be present on the multi-catheter guiding system, delivery catheter, and fixation device, including the proximal elements and distal elements, to name a few.
Further, the system 3 may be supported by an external stabilizer base 1440, an embodiment of which is illustrated in
It may be appreciated that the stabilizer base 1440 may take a variety of forms and may include differences in structural design to accommodate various types, shapes, arrangements and numbers of handles.
